LAWN-SPRINKLER.

Specification of Letters Patent.

Patented Dec. 5, 1905.

. Application filed March 27, 1905. Serial No. 252,114.

apolis, in the county of Marion and State of Indiana, have invented newand useful Improvements in Lawn-Sprinklers; and I do declare thefollowing to be a full, clear, and exact description of the invention,reference being bad to the accompanying drawings, and to the charactersof reference marked thereon, which form a part of this specification.

This invention relates to sprinklers that are designed to be connectedto garden-hose and left to operate on lawns; and it has referenceparticularly to adjustable or changeable devices whereby different formsof sprays may be produced, and it also refers to sprinklers that may bechanged so that they may be adapted to be used for discharging .solidstreams of water, as by-ordinary nozzles.

Objects of the invention are to provide hosenozzles with sprinklingdevices that may be quickly detached therefrom and to provide a varietyof sprinkling devices that may be conveniently adjusted to a nozzle sothat either one of various forms of sprays may be produced at will, and,further, to provide that sprays may be projected either upwardly orhorizontally from a nozzle extended horizontally on the ground.

The invention consists of a sprinkler-head provided with a plurality oftypes of deflecting devices and attached to an arm which is adjustablyand detachably connected to a nozzle; and the invention consists,further, in the novel parts and the combinations and arrangements ofparts as hereinafter particularly described and claimed.

Referring to the drawings, Figure 1 is a top plan view of the completeapparatus; Fig. 2, a longitudinal sectional View thereof; Fig. 3,

a transverse sectional view on the line A Ain Fig. 1; Fig. 4, an endelevation of the complete apparatus; Fig. 5, a side view of the nozzleadapted to hold the sprinkling devices; Fig. 6, a perspective view ofthe sprinklerhead and its supporting-arm.

Similar reference characters in the drawings designate like elements orfeatures.

In construction the various parts may be most cheaply formed of iron.

A nozzle B is provided having a bore 6, the inlet end 6 of which isthreaded to receive a coupling 00 for connecting a hose y thereto, theexterior of the outlet end 0 being a true One side of the nozzle has aboss attached thereto having abearing -face B parallel to the axis ofthe nozzle, and a pivotal stud a is attached to the boss and extendsfrom the bearing-face at right angles thereto, the stud being threadedand having a thumb-nut a and awasher 7 thereon.

The supporting-arm G of the sprinkler devices has an oblong aperture (2in one end thereof adapted to receive the stud a and is clamped to thebearing B by the nut a. At the opposite end of the arm the sprinklerheadis attached thereto and comprises an elbow D, having a face 8 presentedtoward the arm 0, and from the face extends a curved channel 6, adaptedto receive the end a of the nozzle and having a restrictedoutlet-orifice e, at either side of which at suitable distancestherefrom extend pillars f f that are attached to the elbow D, a narrowbridge g being attached to the pillars and supporting a cone E, havingits apex close to the orifice e of the channel 6. The sprinkler-headalso comprises a convex deflector F, attached to one side of the elbowD, and a concave deflector G, attached to the opposite side of theelbow.

The nozzle is provided with a base H, having feet It and h, and isinterposed between the arm C andthe washer 7 on the stud a and isclamped fast by the nut The washer 7 may of course be dispensed with, ifdesired.

In practical use the nozzle will be supported horizontally by the base Hand the hose to which the nozzle may be connected, the feet of the baseresting on the ground, and the nozzle may be drawn toward the person ifone pulls the hose toward himself. If the end 0 of the nozzle be enteredin the channel 0, the spray will be thrown upwardly and spread out inall directions radially by means of the deflecting-cone E. If it bedesired to produce dilferent forms of sprays, the nut a may beslackened, and the nozzle may then be adjusted so as to project a streamagainst either one of the deflectors F or G, as may be desired, asindicated by dotted lines in Fig. 1, after which the nut shouldbetightened. If a solid stream be desired for washing windows or scrubbingpurposes, the sprinkler-head may be moved entirely out of the way of thestream from the nozzle, or the arm C may be detached from the nozzle atwill.

Having thus described the invention, what is claimed as new .is

1. A lawn-sprinkler including a nozzle provided with a pivot at a sidethereof, a supporting-arm mounted on the pivot, a supportingbaseattached to the nozzle by means of the pivot, and a sprinkler-headattached to the supporting-arm and having a curved channel therein and aplurality of diflerent forms of deflectors at either side of the channelindependently thereof, and a deflector at an end of the channel of thehead.

2. A lawn-sprinkler including a sprinklinghead having a curved channeltherein, a concave deflector at one side of the head, a convex deflectorat the opposite side of the head, a conical deflector at an end of thechannel, an arm attached to the sprinkler-head, and a nozzle pivoted ata side thereof to the arm and having its outlet end movable to eitherthe channel or the concave or convex deflectors.

3. In a lawn sprinkler, the combination with a nozzle, of asprinkler-head having a channel therein, pillars attached to the head, abridge attached to the pillars, a cone attached to the pillars oppositethe outlet-orifice of the channel, unlike deflectors at opposite sidesof the head, and a supporting-arm attached to the head and connectedmovably and detachably to the nozzle.

4:. In a lawn sprinkler, the combination with a nozzle, of a pivotalstud attached thereto, a supporting-arm and also a supportingbasemounted on the stud, a binding-nut on the stud, a sprinkler-headattached to the supporting-arm and thereby supported movably adjacent tothe outlet-orifice of the nozzle and provided With a convex deflectorand a concave deflector and also a channel between the deflectors, and adeflector supported at the outlet-orifice of the channel.

In testimony whereof I aflix my signature in presence of tWo witnesses.

HENRY HAMILTON.
